アセトフェノン化合物およびヒドロキシアセトフェノン化合物の製造方法
Document Type and Number:
Japanese Patent JP7296815
Kind Code:
B2
Abstract:
To provide novel methods that can produce desired acetophenone compounds and hydroxyacetophenone compounds at good yields.SOLUTION: An acetophenone compound production method includes a process in which, in an aprotic organic solvent, a first liquid mixture obtained by mixing an acetic anhydride and an aromatic compound of the formula (I) is brought into contact with a Lewis acid, to produce an acetophenone compound of the formula (II) [where R1 is a hydroxy group protection group, R2 is an amino group protection group, and Ar is an optionally substituted aromatic ring group] [where R1, R2 and Ar are the same definitions as in the formula (I)].SELECTED DRAWING: None
